You finally found it. The perfect Cessna 172 or maybe a sleek Cirrus SR22 sitting in a hangar three states away. The pre-buy inspection came back relatively clean, the price is settled, and you’re ready to wire the money. But then someone mentions the FAA Form 8050-2. That’s the official aircraft bill of sale, and honestly, if you mess this one piece of paper up, the Federal Aviation Administration (FAA) will make your life a living nightmare for the next six months.
People think it’s just a receipt. It isn't.
In the world of aviation, the bill of sale is the legal bridge between the seller’s registered ownership and your right to fly. If there’s a typo in the N-number or a stray middle initial that doesn't match the previous registration, the Civil Aviation Registry in Oklahoma City will bounce your application faster than a student pilot’s first solo landing. We aren't talking about a car title here. We’re talking about a federal document that governs a high-value asset in a strictly regulated national airspace.
The Form 8050-2 and Why It’s Non-Negotiable
The FAA is remarkably picky. They don’t want a fancy, custom-designed document you made in Canva. They want the aircraft bill of sale on their specific form, or a document that contains every single piece of information that form requires. Most people just use the official PDF because it’s safer.
Why does it matter so much? Because the FAA operates a "notice-based" registry. They don't actually verify that the seller has the legal right to sell the plane; they just record the documents you give them. If the chain of title is broken—meaning there’s a missing bill of sale from three owners ago—you might "own" a plane that you can’t legally register or fly.
It’s a mess.
I’ve seen deals fall apart because a seller signed as "John D. Smith" when the previous registration was held by "John David Smith." To the FAA, those are two different people. You’ll be hunting down that seller in three weeks, begging for a corrected signature while your plane sits in a hangar collecting dust and tie-down fees.
The "Chain of Title" Nightmare
Let’s talk about the thing nobody warns you about: the title search. Before you ever sign an aircraft bill of sale, you need to know who actually owns the plane. You might be talking to a guy named Dave in a flight suit, but the plane might be owned by "SkyHigh Holdings, LLC."

If Dave signs the bill of sale in his own name, it’s worthless.
Expert escrow agents like those at AIC Title Service or Oklahoma City-based Insured Aircraft Title Service spend their entire day untangling these knots. They look for "clouds" on the title. A cloud could be an old mechanic’s lien from 1994 that was never properly released. Or maybe a bank that went defunct in the 2008 crash still has a recorded interest in the airframe.
You cannot ignore these.
If you buy a plane with a lien on it, you bought the lien too. The aircraft bill of sale transfers the interest, but it doesn't magically wipe the slate clean. Always, always run a title search through a professional service before the money leaves your account.
Common Mistakes That Delay Registration
- Ink Signatures: Even in 2026, the FAA is weird about digital signatures. While they have opened up to some electronic formats, many examiners still look for "wet" signatures or very specific types of digital authentication. If you use a standard "type-your-name" DocuSign without the proper digital certificate, expect a rejection letter.
- The Address Game: The address on your registration application (Form 8050-1) must match the buyer's address on the bill of sale. If you use your home address on one and your office address on the other, the FAA gets confused.
- Incorrect N-Number: It sounds stupid, but people mistype the tail number. Double-check it. Triple-check it.
The Role of Escrow in the Transaction
You wouldn't buy a house by handing a suitcase of cash to a guy on the porch. Why do it with a $250,000 aircraft? Using an aviation escrow service is the only sane way to handle the aircraft bill of sale process.
The process is pretty straightforward:
- Buyer and Seller sign a purchase agreement.
- Buyer sends money to the escrow company.
- Seller sends the original, signed aircraft bill of sale to the escrow company.
- The escrow company confirms the title is clear.
- Escrow files the paperwork with the FAA and releases the funds to the seller.
It protects everyone. The seller knows the money is real, and the buyer knows the paperwork is being handled by someone who knows where the FAA’s bathroom is located in Oklahoma City. It costs a few hundred to a couple thousand dollars depending on the hull value, but it is the best insurance you’ll ever buy.

Dealing with Co-Owners and LLCs
If you’re buying a plane with your buddy, or putting it into an LLC for tax purposes (which you should talk to a CPA about, by the way), the aircraft bill of sale needs to reflect that exactly.
If an LLC is buying the plane, the person signing must have the legal authority to bind that LLC. The FAA often requires a "Statement in Support of Registration" for LLCs to prove who the members are and that they are actually U.S. citizens. Yeah, that’s a big one—the FAA generally requires aircraft to be owned by U.S. citizens or permanent residents. If your LLC has a foreign member, you’ve got a whole different set of hoops to jump through involving voting trusts.
It’s complex. It’s annoying. But it’s the law.
What About the Engines and Avionics?
Here is a weird quirk: the FAA aircraft bill of sale (Form 8050-2) technically only covers the airframe. While it’s understood that the engines and avionics come with it, for high-value turbine engines, there is often a separate bill of sale.
Wait, why?
Because big engines have their own serial numbers and their own maintenance logs that are tracked almost as closely as the plane itself. For a piston-single like a Piper Cherokee, the standard form is fine. But if you’re moving into the world of King Airs or Citations, you’re going to be looking at a mountain of paperwork for every serialized component.
The International Complication
Buying a plane from Canada or Mexico? Take everything I just said and multiply the difficulty by ten. You’ll need a "deregistration" from the foreign civil aviation authority before the FAA will even look at your aircraft bill of sale.

If you try to register a plane in the U.S. that is still registered in the UK, you’re stuck. You’ll be paying for a plane you can’t legally put N-numbers on. This is where professional "delivery pilots" and international title experts earn their keep. They ensure the "Cape Town Convention" requirements are met—this is an international treaty that governs interests in mobile equipment like planes. It’s dense legal stuff, but it basically means there’s a global database of who owes money on what plane.
Actionable Steps for a Clean Transfer
Don't just wing it. If you're looking at a bill of sale right now, stop and do these things:
1. Verify the Seller’s ID
Ask for a copy of the seller’s photo ID and compare it to the current registration. If the plane is owned by "Vandelay Industries," ask for the corporate resolution showing the person you're talking to can actually sell the assets.
2. Use the Official Form
Go to the FAA website and download the latest version of Form 8050-2. Don't use a photocopy of a photocopy from the 1980s. The scanners at the Registry like clean, crisp documents.
3. Set Up Escrow Immediately
Even for a $30,000 Cessna 150, escrow provides a neutral third party. It prevents the "he-said, she-said" drama if the plane develops a massive oil leak during the ferry flight home.
4. Check the "Pink Copy" Rules
Traditionally, you’d keep the pink copy of the registration application in the cockpit as your temporary registration. Nowadays, it’s often a printed receipt from the online filing. Whatever it is, make sure you have it before you take off. Flying without a valid registration (or the temporary proof of one) is a great way to get a ramp check that ends in a massive fine.
5. Update Your Insurance
The second that aircraft bill of sale is signed and the money moves, the risk is yours. Make sure your insurance broker has the new N-number and your name on the policy before the wheels leave the ground.
The FAA Registry is a slow-moving beast. Currently, they are processing registration backups that can take weeks or even months to fully clear the system. Providing a perfect, error-free aircraft bill of sale is the only way to ensure you don't get tossed to the back of the line. Double-check the serial numbers, ensure the names are identical to the previous records, and use a professional title service. It’s the difference between flying your new pride and joy and watching it sit in a hangar while you argue with a government clerk over a missing middle initial.
